Eating disorders are highly sexually differentiated disorders that exhibit a female predominance in risk. Most theories focus on psychosocial explanations to the exclusion of biological/genetic influences. The purpose of this descriptive review is to evaluate evidence from animal and human studies in support of gonadal hormone effects on sex differences in binge eating. Although research is in its nascent stages, findings suggest that increased prenatal testosterone exposure in males appears to protect against binge eating. Although pubertal testosterone may exert additional protective effects, the prenatal period is likely critical for the decreased risk observed in males. By contrast, studies indicate that, in females, it is the lack of prenatal testosterone coupled with the organizational effects of pubertal ovarian hormones that may lead to increased binge eating. Finally, twin data suggest that changes in genetic risk may underlie these hormone influences on sex differences across development.

暴饮暴食中的性别差异:性腺激素对整个发育的影响

饮食失调是高度性别分化的失调,表现出女性占主导地位的风险。大多数理论侧重于社会心理学的解释,以排除生物学/遗传学的影响。这篇描述性综述的目的是评估动物和人类研究的证据,以支持性腺激素对暴饮暴食中性别差异的影响。尽管研究尚处于初期阶段,但研究结果表明,男性增加产前睾丸激素的暴露似乎可以防止暴饮暴食。尽管青春期睾丸激素可能发挥额外的保护作用,但产前期对于降低男性患病风险至关重要。相比之下,研究表明,在女性中,缺乏产前睾丸激素,加上青春期卵巢激素的组织作用,可能导致暴饮暴食增加。最后,双胞胎数据表明遗传风险的变化可能是这些激素对整个发育过程中性别差异的影响的基础。
